Comment (by vdelecroix):
I actually developed the same idea as yours while thinking a bit more
about it. What we want to cache is something like `n -> (k1,OA,k2)` where
`OA` is a OA(k1,n) and `k2` is such that Sage does not know how to compute
OA(k2,n). And this feature looks very specific to design and I do not see
how a decorator can handle that nicely.
So, if you are willing to use these @cached_method everywhere or even the
one you wrote in #16353, there is a need for a big '''TODO''' saying that
it is here for quick-and-dirty speedup.
So let's not talk to much about caching right now, I will look at the
construction.
